Slag Heaps 83 and 94 - Fouquières marshes

A route that takes you through the Fouquières marshes. You'll climb the wooded slag heap 83, offering a view of a mysterious artificial valley. You'll then head for slag heap 94 (staircase slag heap), passing the schlamm bins (storage of mining waste) and the Harnes fishing pond. Return along the path that runs alongside the Lens canal.

Description of the walk

Car park at Rue de la gare d'Harnes in Courrières, south of the canal (before the bridge) turn left towards "Bois de Florimond". Follow the road to the car park.

(S/E) Leave the canal behind and drive around the lagoons to the east. Head south, leaving the lagoons on your right.

(1) In front of you is the wooded slag heap, follow it for a few metres. You'll come to a cycling barrier/gate. Go through it to enter the slag heap site. The path climbs gently into the wood.

(2) At the crossroads, turn right in front of the barrier, then right again at the next intersection.
Continue up the path for a few dozen metres to reach the viewpoint.
This time, at the intersection, take the path on your right, heading south-east then south, until you reach a crossroads.
Variant 1 in practical info.

(3) At the crossroads, take the path slightly to your right, the furthest downhill. The path twists and turns to reach a barrier/gate at Le Tiercé.

(4) Cross the barrier and, at the intersection with wide paths, turn right. You will then pass the slag heap on your right.

(5) At the crossroads, turn slightly left, following the signs for "Bac à schlamm".
Continue for approx. 400m, crossing a road. Continue straight on, and after a wide bend, come to the information sign.
"Variant 2 in practical info".

(6) Cross the road, turn left towards the fishing pond and follow the road. A few dozen metres after the pond is the entrance to slag heap 94.

(7) Enter the slag heap via the old quarry entrance.
Climb clockwise along the slag heap's contours.
At the top, walk clockwise around the plateau, then back down when you reach the uphill path. Return to the slag heap entrance.

(7) For the return journey, head back along the Lens canal, going beside the fishing pond, which you leave on your right.
At the edge of the canal, turn right and follow the canal (on your left) for over 2km to return to the parking lot (E).

Practical information

The walk can be extended at points 3 and 6:
(3) Variant 1: It's possible to make a detour to enjoy another viewpoint, to do this take the path to the right and climb the plateau to its end.
(6) Variation 2: You can walk around the old schlamm tank, following the sign to the left.

If you prefer, you can shorten the walk and skip the ascent of slag heap 94. To do so, just walk around the fishing pond.

You are on a protected site, so take your rubbish with you, and observe but do not disturb the flora and fauna so typical of the coalfield.

Take your binoculars and camera for the views.

If you're on a historic site, respect the memory and find traces of the past.

If you want to join the "Défi Terril Unesco" (51 terrils to climb) or just for fun, you can take a selfie at the top of the slag heap ('terril' in French) and share it with #defiterril and @defiterril on Instagram or by email defiterril@gmail.com.

You can also add your stone to the cairn (pile of stones) at the top of the slag heap and mark your presence at the top of the slag heap forever.

A very nice walk, with no particular problems except at point 3 where it says "At the crossroads, take the path slightly to your right, the furthest downhill..."; it's not to the right, it's to the left.

The two positive points are the wooded section at the start along the Souchez canal and, of course, the Terril and its view over the valley, but it doesn't compare with Terril 74A. The big drawbacks are the almost non-existent signposting and the noise from the motorway right next to the terril.

Lovely route in fine weather.
A varied route with a good mix of hilly, green sections with views, refreshing sections by the water and the unusual, lunar look of the Arena terril with its fitness zones.
A great time.

Great route, the first slag heap is really beautiful. The return journey along the canal is very soothing.

I knew about the Florimond wood and the lagoon, but I'd never been to the Fouquières slag heap. The route is newly signposted by the chain of parks and I enjoyed the walk. I didn't use your guide but I appreciated the extract from the IGN map.
Thank you very much.

A lovely nature walk, exclusively on footpaths, taking in two slag heaps and, from the top, part of the coalfield. It's amazing to see this corner of nature along the mining bypass, which unfortunately can be heard for part of the route. The autumn colours further enhance the scenery. It was also interesting to see the smokestacks that are still escaping from the first slag heap we visited. Thank you for this discovery.
We followed the route using the GPS and the app. No difficulties.
I recommend this tour.

The explanations were very vague, and I had to cut the walk short due to a lack of reliable directions.

A very pleasant, varied and natural family outing
the second slag heap was a great success with our daughters (aged 10 and 12), who enjoyed the "course" aspect of it
there is perhaps a little more difference in altitude in total

A lovely walk for families. I would advise against using a pushchair as there are barriers at the slag heap. Very nice discovery

We had a great time on this hiking trail!
We made the most of the slag heaps and the view from the top of the 2nd slag heap, which is very well laid out.
Lovely setting and a great experience thanks to the description! Thanks a lot!
